To all whom may cortcern:

Be. it known that I, ALBERT PELTz'ER, a

- subject of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented; certain new and useful Im rove-* ments' in Dumping Cars, of which t e following is a specification. This invention relates .to dumping cars having inwardly tilting sections, and. has for its ob ect to provide an improved and mechanically possible structure suitable for railway cars'and capable of being produced in pressed steel or the like, and characterized especially by the fact that the opposite tilting sections are connected together so as-to swing in unison, and are so hung that they close whenempty, and automatically open to dump a load when the latch is released. r

' Further advantages and novelties of construction will be apparent from the following description and the accompanyin drawings. In the drawin s, Figure 1 is a p an view of a car constructs according to the-invention. Fig. 2 is a side elevation. Fig. 3 is a vertical .cross section with the dumping sections closed. Fig. 4'is tions open.

Referring specifically to the drawings, the frame of the car will be. seen to be composed of side sills 2, mounted upon the journal a similar view with the secboxes, and connected at the ends by end sills the side sills 3. Cross sills or bolsters 4 are mounted upon near the end thereof, and-these cross sills support hearing or pivot boxes 5'in which the ends of the pivot bars 7 aresupported.

The tilting sections meet at the middle longitudinal line of the car, and are hung upon the pivot bars 7, and-each section consists of a curved bottom and side 1 and ends 8. The edges of the ends lap each other where they meet, and the meeting edge at the bottom is provided with a lap stri' 10, by which means the joint is closed and Teakage of the contents of the car is revented.

In order to insure the simul I corresponding movement or swing .of both the sections, they are'connected at eachend by a curved link 1'4, of the respective sections, the pivotal points 15 being so arranged with respect to the main pivot 7 that the. said pivotal points each maintain the same distance apart in all positions of the sections, and, consequently,

.tions are loaded the center hook is connected to mec anicallypossible taneous and pivoted at 15 to the ends.

when one swings the other must swingto the sameextent or position.

The sections are'so hung that the center of gravity of each, when they are, closed, is directly below or perhaps a little outside of the pivots 7, and accordingly when the sections are empty they will sWIng closed bygravity,

and in consequence of the connection between the two neither one will be 'apt to stick, becausethe weight of one will tend to assist the other in case either is cl ogged.

Said pivots 7 are so arran ed, however, and the sides 1 are so shaped t of gravity will be inside the pivots 7, and consequently the load will tend to automaticallytilt the sections and dum leased.

The latch consists of a hook 1 1, ivoted to' a hanger 13 near the edge 'of the ottom of one section and arranged to engage the lip 9 at the edge of the other section, and said an operating lever 12 which extends up beside the'end-of the sec.- tion in convenient position to be manipulated from above. One of these be rovided at each end.

he extension of the the section from one en to the other adds greatly to the strength and rigidity. thereof at when the sec- (pivot bars 7 acrosswhenever the latch is re- 4 latches is or may I and enables the sectlon to be made of sheet or structural metal, and of greater length than would otherwise be the case. Said bars tend to prevent buckling, be made of any ordinary or desirable length, are erhaps necessary to terial of ordinary weight.

make the structure for use in carrying maand if the car is to Although, asstated, the'sections'tend'to' I open when loaded, the strain of the whole weight does not come on the latches, because the sides 1 are so shaped that the load is almost balanced directly under the pivots, and consequently the only purpose of the latches is to resist the tendency to open, referred'to.

I claim:

1. The combination with a frame,.of a air of swinging body sections pivoted at t eir ends on the frame, ingosition to swing to and connections .between movable therewlth, and confrom each other, an the sections,

' structed to produce simultaneous correspondmg movement of both sections.

' 2. The combination with a frame, of aair of swinging body sections pivoted at t eir no I nected-between the ends of the opposite sec' tions, to produce simultaneous corresponding movement of both sections.

' 3. The combination with a frame, of e pair of pivoted body sections which swing to and from each other and have meetin edges, one of said edges having a lap strip 0%fset to pass and lap within the other edge when 'swung together.

'4. A dumping car comprising side and end sills mounted on trucks, bolsters extending across upon the side sills, at the ends thereof, and a pair of inwardly-tilting body sections extending lengthwise between the side sills andlntvin continuous pivot bars extending acrods'r'wit 'n said sections from one end to the other and resting at their ends in bearings on the bolsters.

In testimony whereof I afiix my signature, in presence of two witnesses.
